Help with unidentified critters from Mexico

Hi

My name is Rudolf Svensen and i am a photographer living in Norway.

Last summer I spent some time in Akumal, Mexico (East Coast) and I captured a lot of images of the marine life. However I do not have to many books on Mexican marine life, so I wonder if you could help me identefying some of them?

First two types of corals:

Then a sea slug:

A sponge:

A ray:

Something I think must be a wrasse:

And finaly a parrotfish:

All images was taken at shallow water while freediving.

Best Regards Rudolf

The sea slug is T crisspata - the Lettuce Slug.

The orange thingy is a tunicate.

The last two are parrotfish - dunno the species.

The small parrotfish looks like a Red Band Parrotfish (Initial Phase)

I'd guess the first parrot fish is a Redband initial phase. The 2nd I'll leave to those who know.

I agree re the first wrasse - no doubt a Redband PF initial phase. I think the second PF is a Blue Parrotfish, initial phase ie without the squared off bump on its "forehead" that the terminal phase has.

Not sure about the ray - the photo lacks a bit of detail. The shape seems to suggest a Yellow Stingray, Urolophus jamaicensis

Thank you all for your help
